Particulate matter testing from SGS - specialized testing and analysis for diesel and gasoline engines.

Highway in the dark

Determining the particulate matter from your engines is essential for regulatory compliance. As a result, specialized testing is required. We offer a range of methods for collecting and analyzing particulate matter samples for both diesel and newer Gasoline Direct Injection (GDI) engines.

Why choose particulate matter testing from SGS?

We offer you:

  • Accurate testing for diesel and gasoline engines 
  • Complete particle number and particle size distribution reports 
  • Standard particulate mass quantification 
  • Analysis of engine-out particulate filters for volatile organic compounds (VOCs) via the vacuum sublimation method
  • Characterization of particle emissions over a wide range of altitudes and temperatures 
  • Analysis of the sources of variability in particle emissions to aid in component development and control system calibration
